[@TabooGroundhog]

uHm aCtUaLlY if a second is based on the time of the universe and not the time of an individual seconds just feel longer or shorter instead of there being more or less seconds. So the time crisis in Africa is still a very real thing

[@Coregame3]

no

[@dead_unicorn6074]

Well it is actually a lie because time is relative and can be described by general and special theory of relativity. So basically time is changing when you speed up and slow down and when gravitational conditions change. Since every point on earth have different altitude relatively to sea level linear velocity of this point is also different(due to the same angular velocity and different distance between surface and center of the earth), also different elements and minerals under the surface affect gravity in every individual point on earth. Both of these properties in combination give you different time dilation relatively to the sea level in any given point on earth. So time 'passes' differently in Africa and other parts of the world.

For that to be true, an entire parallel universe would be created from every disturbance of the past. So living in a universe without some kind of altercation to the past having occurred would be hardly possible due to the vastness of the universe. With near certainty, we can conclude that if a new universe was generated for every past time disturbance, we are living in one that has possessed one.

Jenner discovered a vaccine for smallpox yes, but according to Wikipedia, the smallpox vaccine was a naturally occurring weaker form of the disease. What Pasteur did was creating artificially weakened forms of anthrax and chicken cholera. It seems that it was Pasteur who gave it the name "vaccine" in honour of Jenner's discovery.

[@vaibhavkumarsingh5371]

1:00 explaining your mom that PUBG can't be paused.

[@4Gehe2]

I have always imagined it like this: Time is linear and moves at "constant pace", even if time is relative that moment in space and time moves constantly at the same rate. If you go back in time 1 year, change something and spend 0.1 year in past, you return 0.9 years to the future, so to the same exact point. Then you haven't returned to a point in which the time wouldn't have changed. Since the point of observation is you. If you'd want to live in the changed past you'd have to travel back 0.9 to 0.999... years from that point, so with in the ripple. Imagine it like a train. You go to the last carriage, set something in motion at the exact speed of the train, you go to the first carriage, the whatever is in motion will never reach you since you move constantly away from it at constant pace. So to feel the change you need to go back to the last carriage. If you move faster than speed of light, to actually observe the light you left behind, you have to go backwards in space.

[@fleskenialation]

This makes too much sense

[@ericselectrons]

You've just recreated Einstein's thought experiment. ;)

[@AnonEMus-cp2mn]

Does the "speed" of time act like a moving particle (as your example has stated), or could it act like a wave? in which the materiality of "time" exists everywhere, but its "speed" is an illusion, merely a transfer of movement in a certain direction. In this case, even tough someone can't match the speed of this wave, they could still perceive its effects by the location of time it interacts with? to put it simply, a wave isn't the water moving at the direction and speed of a wave, it is only the transfer of energy between water which remains relatively stationary.

[@AnonEMus-cp2mn]

I am still attempting to grasp this concept, but your description seems to have answered my question. in terms of speed as a particle or a wave, to better simplify it I was referring to the nature of what makes a wave different from a particle in 1 dimensional thinking. a particle (like say a dot) travels in a certain direction, the dot is moving and the effects of motion come from the dot's location. a wave (imagine a series of dots on a single axis line) travels in a certain direction, an activity (a wave) travels in a certain direction passing through the dots, each dot does not move from its location, yet the wave is the one actually "moving" the effects of motion are independent from the dot's location. if a perspective cannot catch up to the time frame ahead of it (like the train acting like a particle) then I couldn't sense the motion of a wave if I am swimming at the same speed behind it *even though I am occupying the same water it flowed through*. I could only sense a disturbance that occurred ahead of me if the wave made a notable change to the "water" it passes through, but then again I can only know there is a difference if I knew what the "water" was like before the wave encounters it.

Thanks for sharing your train of thought. Apart from the first sentence, this is exactly how I understand it. This is, like mentioned before, exactly what it means for time to be relative, it is only something we perceive. Afaik, causality is the common denominator. (At least, I got that far into understanding PBS Space Time's videos.) (@ Henri)

I love the cinematography this vsauce channel employs. It's always interesting, especially during the intros. (thank you cryptid)

Just a little correction: the word you're looking for is cinematography. Filmography is a resumé of the films you've made.

I like thinking of time travel as travel to different universes in the infinite multiverse. For example; if you wanted to travel to the year 19xx from 2018, you’d simply be traveling to universe that was experiencing the year 19xx at the same time your universe was experiencing 2018.

[@arandomperson7676]

Most probably multiverses don’t work like that..

[@markozaja2001]

If that's the case, than universe is stucked in time, any of them.. That's brings us to theory that we are too stucked in time or we just jump from one to another but im sure that's impossible

[@markfourtwenty9897]

NDGT seems smart but I watch him many times and I see flaw from his explanation...This video for example when they talk about the movie "The Time Machine"....He don't understand why the GF of the time machine inventor always die every time he goes back in time to save her.....The death of GF is reason why protagonist invent the TM in the first place...so he cannot save her using the TM...

[@katiekatie6289]

mark fourtwenty That doesn't make sense. Either you can change history or you can't. The idea that he would need to have invented a time machine to be able to go back in time in the first place rests of the premise of there being a single timeline. However, the fact that he's able to change anything to begin with demonstrates the opposite. The idea that you can chance history, *except* when it prevents you from changing history in the first place, is preposterous and rests on contradictory premises.

[@markfourtwenty9897]

Katie Katie...Space-time continuum..You can change any event in the past as long as if won't affect the present you...The protagonist in the movie can change many things in the past but he can't change the death of her fiancee because her death is the reason for the creation of the machine...If the girl don't die, the time machine will not be created, so he can't go back in time in the first place...It makes sense to me..I felt bad for you :)

Going back exactly 30 years would still land you in a problematic situation. The Solar system moves relative to the Milky Way and the Milky Way moves relative to other galaxies. You'd still be in the middle of nowhere, in the vacuum of empty space.

Tekno Axe the problem with that logic is that when you freeze time, you're no longer in the same dimension. You enter a space-time dimension, and for all we know(maybe we know?) it has no effect.
